Abstract: Disclosed is a transferred arc plasma torch in which a tubular anode is mounted in a bore at the lower end of a barrel of the torch, the bore being formed at a preselected angle to the axis of the barrel. The cathode is a length of tungsten rod which is held in a coaxial relation with the anode by cementing the end of an electrode holder, which mounts the cathode, into an insulating tube which extends through the barrel and forming a silicone rubber sleeve between the insulating tube and a bore formed in lower portions of the barrel such that the sleeve adheres to the insulating tube and the barrel. The silicone rubber sleeve and the cemented connection between the insulating tube and the cathode holder are formed adjacent one end of the anode so that the cemented end of the electrode holder is substantially fixed in relation to the anode.
